To all whom it may concern,.-

Be it known that I, RAYMOND B. PRICE, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new'and useful Improvements in Rubber Vehicle-Tires;and I do hereby declare the following to be a full, clear, and eXactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the saine.

This invention relates to a novel construction in a rubber Vehicle-tire,the object being to provide a tire which can be vulcanized in greatlengths and secured to the wheel in a very simple and efficient manner;and it consists in the features of construction and combinations ofparts hereinafter fully described and claimed.

In the accompanying drawings, illustrating this invention, Figure 1 :isa transverse section of a tire'and rim constructed in accordance withmyinvention, showing same mounted upon the fellyof awheel. Figs. 2, 3,4, 5, 6, 7, 8, 9, and 10 are transverse sections of modified forms ofthis invention. Figs. 11 and 12 are detail views showing two forms ofwire-cloth stiftening-strips adapted to be intermolded in the baseportion of the tire.

This invention consists, essentially, in providing Within the rim A asupplementary sheet-metal rim B, preferably of a non-corrosive metal,the anges of which project beyond the flanges ofthe rimA and are adaptedto be bent over inwardly to engage thebase portion of the tire C. Thesaid supplementary rim B is firmly secured within the rim `Ain anysuitable manner,but preferably by means of the screws or bolts D,securing the rim A to the felly E. The base portion of said tire C ispreferably stiened either by intermolding a suitable stiffeningmaterial, as shown in Figs. 1, 2, 4, 5, 6, and 7, or by vulcanizing saidbase portion to a greater degree than the tread portion, as shown inFig. 3. For stiening said base a wire-cloth strip is preferably used, asshown in Figs. 1 and 2, and the particular form of wire-cloth shown inFigs. 11 and 12 is most desirable, for the reason that in this form thelateral wires F are practically straight and uniformly spaced and arefirmly .bound together by longitudinal wires G, separated by spacesgreater than those between the lateral wires. The said longitudinalwires G are either twisted about each other and about the lateral wires,as shown in Fig. 12, or run parallel and in close contact with eachother, their convolutions being alternated -to cause them to pass overand under each of the lateral wires. description is advantageous, forthe reason that its Weight per square inch is Vconsiderably less thanthat of the ordinary wirecloth and it better serves the purpose oflaterally stiffening the' tire, which is desired, the longitudinal wiresserving only to keep the lateral Wires-in place. The longitudinal Wiresm-ay also be secured to ,the lateral wires by.

means of electricwelding, brazing, or other suitable means. The saidstiening-strips intermolded in said base portion of the tire may bemultiplied to secure any desired hard# ness Ain said base.

In mounting said tire the rim A and auxiliary rim B are mounted on thefelly of the wheel. The tire. C is then inserted and itted', andprojecting edges of the lianges of said auxiliary rim B are then bentover to engage the tire. If it is desired to repair the tire C, saidedges `of the auxiliary rim can be-easily bent back to release the tire.Y

The supplemental rim Bis made from sheet metal or other material capableof being bent at its edges to secure the tire and yunbent to release thesame, whereby the work of vapplying the tire'and` replacing worn tiresis greatly facilitated. The construction of the present wheel-rim is,`such as will preclude bending of the flanges without danger of fracture;but by reason 'of my supplemental rim the main rim is left intact, andconsequently retains its strength.

The particular advantages of this method of fastening are that the tireis absolutely preallcutting of the tire is prevented, that the tire canbe easily removed for purposes of repair, that it cannot be torn out ofthe rim by any lateral or torsional strains to which it may be subjectedand that it cannot travel Wire-cloth of this vented from rolling'in therim, and thereby 95 around the rim, and that any lateral strain isdistributed over -the entire base, thereby decreasing its intensity.

The application of this tire is so simple that any person can do it, nospecial tools or machinery being required.

I claim as my inventionl. In a vehicle-tire, the combination of a wheelrim or channel; a rubber tire, and a supplemental rim or channel securedto the wheel rim or channel and receiving the tire, the ange edges ofthe supplemental rim or channel being bent over to engage the tire afterthe insertion of the latter.

2. In a vehicle-tire, the combination of a Wheel rim or channel, arubber tire, devices intermolded in the tire and extending laterally tothe surface thereof, and a supplemental rim or channel secured to theWheel rini or channel and receiving the tire, the fianged means in thetire holding the Wires regularly spaced, and a supplemental rimor'channel secured to the Wheel rim or channel and receiving the tire,the flanged edges 0f the supplemental rim or channel being bent over toengage the Wires after the insertion of the tire.

In testimony whereof I affix my signature in presence of two witnesses.
